Earth, 2512 A.D. Humans have spread across the six arms of the Milky Way galaxy. The Unified Authority controls Earth's colonies with its military made up almost entirely of clones -- until civil war breaks out. Now the U.A. struggles to survive after a devastating attack cut its communications and left its fleets isolated... Wayson Harris was one of thousands of clones born and bred to be the ultimate soldiers. But as an outlawed model, he was different from the rest -- possessing independent thoughts and an addiction to violence. Stranded on a frontier planet, Harris is desperate to get back to civilization -- and back into the fight. But the rebel factions are warring among themselves, and Harris is contacted by a group that wants to return to the Unified Authority's command and protection -- and they want Harris to deliver their offer of allegiance. Unable to resist the thrill of battle, Harris finds himself in the uniform of a U.A. Marine once more, leading a strike against the enemy. But the rebels have a powerful ally no one could have imagined...
